Climate change and its effect on our oceans


There are multiple threats surrounding our oceans and climate change is a major factor. To begin, ocean acidification is a very serious issue who threatens the marine life. Acidification is caused by the excess carbon dioxide released into the atmosphere which amongst other things effects the growth and colonization of coral reefs. Another threat to coral reefs is the warming of the oceans which causes them to bleach and makes them more at risk of developing diseases which often also leads to their death. Ocean acidification also stops marine animals from building their protective shells and skeletons. Another major threat is the oil spills in the oceans which sticks to the animal’s feather and makes them stuck, they may also ingest oils which is very dangerous and potentially fatal for them. Oil on the ocean’s surface also blocks the sunlight from entering and stops sunlight from reaching the bottom. This does not allow from photosynthesis and leads to the death of many marine plants. Plastic waste that ends up in oceans are often consumed by marine animals. Toxins from the waste enters many species and the entire food chain is influenced, even ending up in human beings which can be dangerous.

 Phytoplankton is the base of all marine life and is the base of many food chains. Phytoplankton levels have decrease by 40 percent in the last century (Connor, 2010) this is mainly related to rising sea temperatures and global warming. Phytoplankton floats at the surface of the oceans and use photosynthesis to grow and survive. They also provide us with a large part of the oxygen we consume and is essential to the oceans survival. Warmer oceans are stopping nutrients from reaching the phytoplankton and is causing them to die. Warmer oceans also leads to more storms, changes the density levels, water movements, melts ice caps in poles which rises sea levels and in turn can cause flooding. Climate change is also causing the extinction of multiple marine animals. In result, many species are forced to move more towards the north and live in deeper waters in order to survive. Overfishing is another major threat to marine life. Some of the species who are most at risk are certain penguin species, polar bears, the orange-spotted filefish…

You’re right, that’s a good point about his fact that have more consequences affecting the oceans. Personally, I think they can affect the coral and marine animals can disappear or destroyed very soon. They can be hurt because of the waste which human beings causes in the oceans. This ecosystem is heavily influenced by the consequences. Also, I totally agree that the climate change is causing problems for the marine animals. The animals can not survive in the changing environment. I think we need to educate people because the ocean is an important ecosystem and the problem is due to human activity. We should inform the population about this so they can take better actions for the environment. I believe that his problems could be resolved by education. What is the next step for the future?
